+1. Can also reproduce this. I find it much easier to reproduce when mass converting upgrades to omni-gel. 2/2 times, when converting probably more than 15 upgrades at once. When it happens, an "undefined" text appears in the screen, and controls become unresponsive.
Yep, I've never had this happen with single-item breakdowns.
I avoided breaking all items down at once, if I had e.g. 16 shotguns, I only marked 15 for breakdown, so the selection could jump to an actual item, then I broke it down separately. That seemed to help the situation, though it makes an already horrible system even more of a chore.
